A. Associative property of addition
B. Inverse propert. Of multiplication
C. Communtative property of multiplication
D. Communtative property of addition

2. Which property is illustrated by the statement? 5.4 + 3 = 3 + 5.4

A. Associative property of addition
B. Inverse propert. Of multiplication
C. Communtative property of multiplication
D. Communtative property of addition

Answer 1

(1) it is (C) the commutative property of multiplication: a*b = b*a, so 2*(-6/7) = (-6/7)*2

(2) it is (D) the commutative property of addition: a+b=b+a, so 5*4+3=3+5*4

commutate = "swap around"
